ETFE (ethylene-tetrafluoroethylene) fluoroplastic is available as pellets or as powder for rotational molding. ETFE resin combines superior mechanical toughness with an outstanding chemical inertness comparable to that of fluoroplastic resins. ETFE features easy processibility, a specific gravity of 1.7, and high-energy radiation resistance. Most grades are rated for continuous exposure at 150°C based on the 20,000-hr criterion.
